Position monitor and alarm apparatus for reducing the possibility of sudden infant death syndrome (SIDS)
First Claim
1. Apparatus for reducing the possibility of sudden infant death syndrome in infants by alerting a care-giver that an infant has moved out of the safe supine position, comprising:
- a. a source of radiation directed generally onto said infant;
b. a reflector configured as a portion of or affixed to a garment worn by said infant, other portions of said garment having different reflective characteristics with respect to said radiation;
c. a radiation-sensitive sensor for providing a first signal varying responsive to changes in the amount of said radiation incident thereon;
d. means responsive to said first signal for producing and transmitting a second signal responsive to the sensed position of the infant;
e. a remote receiver responsive to said second signal for producing an alarm alerting a care-giver if said infant assumes a predetermined position.

Abstract
A device for reducing the possibility of sudden infant death syndrome (SIDS) comprises a position-indicating device effectively coupled to a signal-producing circuit and attached to the clothing of the infant. The position-indicating device provides signals varying in response to prone and other positions assumed by the infant during sleep, allowing an associated alarm device to be activated in response to the infant'"'"'s assuming a SIDS-dangerous prone or side-lying position. In one embodiment, the position of the infant can be determined by an optical sensor interacting with a reflective or other marker adhered to the infant. Gravity or pressure switches may also be used to provide position-responsive signals. A signal generated upon assumption of the SIDS-dangerous prone or side-lying positions is transmitted to a remote receiver located proximate the infant'"'"'s care-giver whereupon an alarm is generated to indicate the need to reposition the infant. A constant low-level or intermittent maintenance signal can be produced to assure the continued and proper operation of the apparatus. An additional awakening alarm can be produced near the sleeping infant to further reduce the likelihood of a SIDS event.

14. Method for reducing the possibility of sudden infant death syndrome in an infant by alerting a care-giver that the infant has assumed a potentially dangerous position, comprising the steps of:
-
a. directing a source of radiation of predetermined wavelength onto said infant; b. affixing a member reflecting said radiation of predetermined wavelength to the infant, such that amount of said radiation reflected by said member varies with the position of the infant; c. providing a detector to receive said radiation of predetermined wavelength reflected from said member and produce a first signal proportional to the strength of the reflected radiation thereby indicating the position of said infant; d. transmitting a second signal responsive to said first signal to a remote receiver; and e. producing an alarm in response to receipt of a second signal indicating the possibility that the infant has assumed a potentially dangerous position. - View Dependent Claims (15, 16)

17. A garment to be worn by an infant while sleeping, and for use in combination with a source of radiation of predetermined wavelength and a detector thereof, said detector being adapted to activate means for providing an alarm signal to a remote caregiver when the detected intensity of radiation from said source falls below a predetermined level, said garment having a portion made of material relatively reflective of radiation of said predetermined wavelength, the remainder of said garment being made of a material relatively absorptive of said radiation of said predetermined wavelength.
